Skeptical Science New Climate Research for Week #26, 2019
Posted on 2 July 2019 by SkS-Team
Welcome to another heaping helping of research publications related to climate change drivers and mechanisms, the effects of climate change and how we might yet grope our way into systems approaches to dealing with the mess we're making, despite ourselves.
52 items this week, derived from some 277 abstracts/articles emerging from our raw feed filter and evaluated for salience and impact.
Skeptical Science was founded to help people wade out of the swamp of misinformation found in public discussions of climate change. A perennial feature and expedient go-to of science denier arguments has been the seemingly paradoxical behavior of sea ice around Antarctica, with ice coverage stubbornly holding and even increasing slightly for the past few decades even as the rest of the ocean/atmosphere system and dependencies showed obvious, growing signs of stress. There are good reasons for this seeming conundrum, but perhaps we're encountering limits to those controls. NASA GSFC researcher Claire Parkinson sums up recent details in the PNAS article A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the rates in the Arctic.

Solved, thanks.
Thanks again to the SkS team to continue the research list!!
I also like bringing the "opener" to the main SkS theme:
Getting skeptical about global warming skepticism ..
The categories bring interesting new aspects of viewing ..
I highly value this hard work of viewing, filtering, prioritizing,
categorizing, doing .. this list is unique in the internet, afaik.
Deep bowing (will continue to donate/advertise as much
as possible/useful .. finite money/attention of people ..).
Virtual hug to the whole team.
"A Positive Iris Feedback: Insights from Climate Simulations with Temperature Sensitive Cloud-Rain Conversion"
This paper---which has topnotch authors---appears to have real importance to the public understanding of our climate future, and is thus newsworthy. Who is going to write a good review, that gives the full story and what it means?
[PS] What is your basis for "top-notch" authors? The involvement of YS Choi would ring some alarm bells given previous shoddy papers (LC09, LC11).
According to the abstract, new modeling suggests that the precipitation efficiency in a higher temperature regime may be higher than has been assessed so far, and that a corresponding decrease in cirrus (high altitude, ice clouds) shielding of downwelling SW radiation could be a consequence of that, providing a positive feedback that could be significant, but it is a very tentative finding. The abstract concludes:
"These results suggest a potentially strong but highly uncertain connection between convective precipitation, detrained anvil cirrus, and the high cloud feedback in a climate forced by increased atmospheric carbon dioxide concentrations."
campcarl - According to the abstract of that paper, they:
So they are running simulations with a postulated but unsupported iris feedback, a mechanism postulated by Lindzen many years ago in a series of debunked papers, and seeing how that affects a simplistic climate model.
I really don't see how that's particularly newsworthy.
Agree with KR.
Thanks for pointing out my mistake. I thought two of the authors were of a more reliable sort for quality work.
